There is no Groupware for me
I want to know if there is a Groupware (or, at least, something that is not called Groupware but does what I want) which has the following features:
- Beautiful, efficient and comfortable web-interface
- Low resource usage (server RAM and CPU)
- Calendar is iCal/WebDAV accessible
- Contacts are LDAP or (even better) WebDAV accesible (GroupDAV, what are you?)
- Uses Mozilla Thunderbird as client (it's nice and portable)
- Can synchronize contacts and calendar with cellular phone (syncML)
